1. A tracer was injected as a pulse to a non-ideal reactor and the exit concentration was measured as a function of time, resulting in the data show in the table t(min) 0 1 2 3 4 5 6 7 8 9 10 12 14 C(g/m^3) 0 1 5 8 10 8 6 4 3.0 2.2 1.5 0.6 0 (a) Construct figures showing C(t) and E(t) as functions of time. (b) Determine both the fraction of material leaving the reactor that has spent between 3 and 6 min in the reactor and the fraction of material leaving that has spent between 7.75 and 8.25 min in the reactor (c) determine the fraction of material leaving the reactor that has spent 3 min or less in the reactor.
